Larsen Engineering works on many sites located on steep hillsides in Marin County. These projects often require extensive retaining walls as a part of the foundation itself. Additional retaining walls are typically needed for surrounding landscape, driveway, and parking areas.

We use the project Soils Engineer’s findings for foundation design, including size and depth of drilled piers for anchorage into bedrock, size of footings, and for the most difficult sites, “soil nails” or high-capacity tie-backs.
